National wikipedias still have to bear English sorting order, which orders the accented characters
outside of normal sort which is "not acceptable" for the languages.
This problem is most visible in the rise of Categories, but present in every automatic list, like
Allpages or the list of registered editors.
I would guess either mySQL or PHP can utilise national locales/collation orders which would simply
require the sites to specify their locale and there we go. Or do I guess it wrong? (I am only
familiar with perl and postgres, where this works.)
